Seeing polarons at a metal oxide surface
Polarons in metal oxides play a key role in processes such as catalysis, high temperature superconductivity, and dielectric breakdown in nanoscale electronics. For this reason, numerous studies have been conducted on technologically relevant oxide materials in which...
Ultrafast control and detection of magnetic correlations in a 5d transition metal oxide
Understanding how the electronic and magnetic properties of materials are modified by the injection of charge carriers is of central importance across a range of fundamental and applied research. For example, the selective doping of impurity atoms into semiconductors...
When magnetism meets topology
The search for exotic particles is one of the most fascinating pursuits of modern physics. While this area of research is traditionally associated with elementary particles created in high-energy physics, simple ‘quasi-particles’, with sometimes highly unconventional...
